Parameter Description Unit
Milling direction 
Climb milling: Mill thread in one cycle.

Conventional milling: Mill thread in one cycle.
 Climbing - conventional: Mill thread in two cycles: rough cutting is performed by
conventional milling with defined allowances, then finish cutting is performed by
climb milling with milling feedrate FS.
FS Finishing feedrate - (only for climbing - conventional milling) mm/min
mm/tooth
8.1.9 Positioning and position patterns
Function
After you have programmed the technology (cycle call), you must program the positions.
Several position patterns are available:
●
Arbitrary positions
● Position on a line, on a grid or frame
● Position on a full or pitch circle
Several position patterns can be programmed in succession. They are traversed in the order
in which you program them.
Note
The number of positions that can be programmed in the one "Positions" step is limited to a
maximum of 400!
Programming a position pattern in ShopMill
Several position patterns can be programmed in succession (up to 20 technologies and
position patterns in total). They are executed in the order in which you program them.
The programmed technologies and subsequently programmed positions are automatically
linked by the control.
Approach/retraction
1. Within a position pattern, or while approaching the next position pattern, the tool is
retracted to the retraction plane and the new position or position pattern is then
approached at rapid traverse.
2. With technological follow-up operations (e.g. centering - drilling - tapping), the respective
drilling cycle must programmed after calling the next tool (e.g. drill) and immediately
afterwards the call of the position pattern to be machined.
